I was looking for a way to keep journal on computer.
It has to be searchable, contain images, and survive a very very long time.
I want to be able to conveniently search and read past journal entries that I wrote decades ago.
Although tags are desirable, it is not essential because I can just search for text.
Web apps and mobile apps may not survive even a decade or two, so I started looking for document formats with open specifications.
It is not easy to search lots of .odf files, but I can just extract texts from plaintext CommonMark files.
It seems CommonMark fits my criteria. I can write in CommonMark, but there is no easy way to conveniently search and read journal on my machine.
Is there a software that helps me with keeping journal in CommonMark?
